Sezvinoratidzwa nemusoro wenyaya,magirazi emhando dzakasiyanadzakanakira kutora mifananidzo yemhuka dzesango uye parizvino ndeimwe yesarudzo dzemalenzi anonyanya kufarirwa mukutora mifananidzo yemhuka dzesango. Kuchinjika kwefocal length, kumhanya kwekutarisa, uye kugadzikana kwemifananidzo yemalenzi evarifocal zvinobvumira vatori vemifananidzo kutora mifananidzo nekukurumidza nguva pfupi yemhuka uku vachichengetedza daro rakachengeteka, zvichivagonesa kubata nharaunda dzesango dzakaoma uye dzinogara dzichichinja.
1.Zvakanakira zvikuru zvelenzi yemhando dzakasiyanaes yekupfura mhuka dzesango
(1)Hapana chikonzero chekuchinja ma lenses kakawanda: Mhuka dzesango dzinowanzo wanikwa nyore nyore, uye unogona kupotsa mukana wekutora mufananidzo wakakosha kana ukachinja kuenda kune lenzi yekutarisa yakagadzika. Kushandisa lenzi ye varifocal kunokutendera kuti ugadzire mufananidzo nekukurumidza nekugadzirisa urefu hwe focal, senge kuchinja kubva pane panoramic view kuenda kune iri pedyo, pasina kuchinja lenzi.
(2)Inochinjika kune zvakasiyana-siyana zvinodiwa pakupfura: Uchishandisa lenzi ye varifocal, unogona kushandisa magumo e telephoto (senge 200mm zvichikwira) kutora mifananidzo yemhuka dziri pedyo, kana kushandisa magumo e telephoto ari pakati nepakati (senge 70-100mm) kutora mifananidzo yemhuka nenzvimbo yadzo, uchiratidza nzvimbo dzezvakatipoteredza.
(3)Deredza mutoro wemidziyo: Zvichienzaniswa nekutakura malenzi akawanda akasimba (akadai se300mm, 400mm, 600mm), lenzi imwe chete ye telephoto varifocal (yakadai se200-600mm) inogona kufukidza urefu hwakawanda hwe focal, ichideredza huremu hunotakurwa uye ichibatsira kuteverwa nekutorwa kwemifananidzo kure kure musango.
(4)Deredza kuoma kwekupfura: Pakupfura mhuka musango, zvinowanzodiwa kuti ugare wakavanzika, zvichiita kuti zviomere vafotori kusvika pedyo nemhuka. Mugumo we telephoto we varifocal lens unogona kushandiswa kupfura uri kure, kudzivirira kukanganisa mhuka, kuderedza kuoma kwekupfura, uye zvakare kuve nechokwadi chekuti munhu akachengeteka.

2.Maitiro ekusarudzalenzi yemhando dzakasiyanazvakakodzera kutora mifananidzo yemhuka dzesango?
Kutora mifananidzo yemhuka dzesango kune zvinodiwawo chaizvomagirazi emhando dzakasiyana; haasi malenzi ese evarifocal akakodzera. Zvinotevera zvinofanirwa kutariswa nokungwarira:
(1)Fkureba kwemaziso
Kureba kwefocal ndiko kwakakosha pakusarudza lenzi yevarifocal; kureba kwefocal kwenguva refu kunowanzoonekwa sekwakanaka mukutora mifananidzo yemhuka dzesango. Vatangi vanowanzo sarudza nzvimbo yefocal urefu hwe70-300mm kana 100-400mm, yakakodzera kupfura mhuka hombe dzisingatyi kana dziri pedyo, zvichibvumira kuenzana pakati pekutora mifananidzo yemhuka nenzvimbo.
Vazhinji vevafotori vane hunyanzvi vanosarudza nzvimbo dzemafocal length dzakadai se200-500mm kana 150-600mm, dzakakodzera kutora mifananidzo yemhuka diki kana shiri dziri kure. Mamwe malenzi anoshandawo nema teleconverters, zvichiwedzera urefu hwefocal kusvika 800mm kana kunyange 1200mm, zvichipa kugona kukuru kwe telephoto.
(2)Aperture
Saizi yeAperture chinhu chakakosha chekufunga nezvacho pakusarudza varifocal lens. Variable aperture lenses dzakadai se f/4.5-5.6 uye f/5-6.3 dzakareruka uye dzinodhura zvishoma, zvichiita kuti dzive sarudzo yevanhu vazhinji. Zvisinei, dzine ma aperture madiki pamagumo e telephoto, zvichida mwero wechiedza wakakwira.
Magirazi enguva dzose anobata chidzitiro, akadai se f/2.8 ne f/4, anoita basa rakasimba asi anodhura uye anorema. Aperture yakakura inowedzera chiedza chinopinda, zvichiita kuti shutter imhanye nekukurumidza, kudzivirira mifananidzo isina kujeka, uye zvakare inoita kuti nzvimbo yacho ive yakadzika, ichiratidza chinhu chakaita semhuka.

(3)Kugadzikana kwemufananidzo uye mashandiro e autofocus
TerefotomagiraziDzinowanzo sviba nekuda kwekuzungunuswa kwekamera, zvichiita kuti kugadzikana kwemifananidzo yakavakirwa mukati kuve kwakakosha! Zvinokubatsira kushandisa kumhanya kweshutter kunononoka paunenge uchitora mifananidzo yakabata ruoko kuti uwane mifananidzo yakapinza. Panguva imwe chete, sisitimu ye autofocus inokurumidza, yakanyarara inonyatso tevera zvinhu zvinofamba yakakoshawo pakubata shiri dziri kubhururuka kana mhuka dziri kumhanya.
(4)Kurema uye kutakura
Kutora mifananidzo panze kunowanzoda kufamba netsoka, uye huremu nehukuru hwelenzi zvinokanganisa zvakananga kurovedza muviri. Kana uchida kutora mifananidzo parwendo rurefu, unofanirwa kufunga nezve dhizaini yakareruka yelenzi kana kushandisa muviri welenzi yekabhoni fiber. Kana zvichidikanwa, uchafanirawo kushandisa tripod yakareruka kana monopod.
Huremu uye kutakura zvinhu zvakare zvinhu zvekufunga nezvazvo pamalenzi emhando dzakasiyana.
(5)Kuramba kwemamiriro ekunze uye kuvimbika
Pakutora mifananidzo musango, kuramba kwelenzi yekunze kunofanirawo kufungwa nezvayo. Lenzi inoshandisa dhizaini yemukati me zoom (hurefu hwelenzi hunoramba hwakachinja painotora zoom) kubatsira kuchengetedza nzvimbo yakadzikama yegiravhiti uye inopa dziviriro iri nani yeguruva nehunyoro; chimiro chinodzivirira guruva nemadonhwe emvura chinogona kuramba chakavimbika munzvimbo dzakaoma dzakadai semasango emvura nemasango.
Mukupedzisa,magirazi emhando dzakasiyana, nekuchinjika kwavo, nyore kushandisa, uye kugadzikana kwemifananidzo, zvave chimwe chezvisarudzo zvikuru zvemalenzi ekutora mifananidzo yemhuka dzesango.
Pakutora mifananidzo, kuchinjika kwe zoom kunogona kushandiswa kubata nekusaziva kwemhuka, pamwe chete nekumanikidzwa kwemagumo e telephoto kuratidza nyaya yacho uku uchichengetedza nyaya yezvakatipoteredza; pamwe chete ne autofocus inokurumidza, tekinoroji yekusimbisa mifananidzo, uye kuumbwa kwayo kwakakodzera, mwero wekubudirira kwekutora mifananidzo yemhuka dzesango unogona kuvandudzwa zvakanyanya.
